IMPROVEMENT IN TlRE-UPSETTING MACHINES. f

Specification forming part of Letters Patent No. 221,066, dated October 28, 1879; application filed June 26, 1879.

To all whom it may concern:

Be it known that I, WILLI'AM HOLDSWORTH, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, haveinvented certain new and usefulImprovements in Tire-UpsettingMachines and 1 do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The nature of my invention relates to certain improvements upon the tire-u psettin g machine for which Letters Patent No. 169,265 were granted to me October 26, 1875, as will he hereinafter more fully set forth.

In order to enable others skilled-in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure 1 is a side elevation of the machine with the side plate removed. Fig. 2 is a section of the upper part of the machine. Fig. 3 is a plan view of the same. Fig. 4 represents the die for the punch from the front. Fig. 5 represents the same from the back.

The box or case of my machine consists of two side plates, A 13, between which the operating mechanism is located. Between these side plates is a stationary bed or jaw, O, and a movable bed orjaw, D.

Below the stationary bed 0 is pivoted an elbow-lever, E, the outer end of which is made in socket form to receive the operating-lever, and this latter lever may be of any desired length to obtain the required purchase.

The inner short arm of the elbow-lever E is, by a link, F, connected with a lever, G, pivoted between the side plates.

The upper end of the lever G forms a head, a, which works in a slot or mortise, a, in the movable bed D, for moving the same to and from the stationary bed.

By this construction I obtain a direct and positive motion of the bed D without any lost motion, as is always more or less the case when links are used.

11'!) are the pivotbolts ot' the levers E and G, whichbolts also connect the side plates, as shown.

From the back plate, A, extends a standard, H, and a similar standard extends from the movable bed D. To these standards are pivoted the levers I I, which have their lower ends corrugated and their upper ends connected by bars J, in the same manner as de scribed in my former patent above referred to.

In the upper surfaces of the beds 0 D are made recesses 00 a: for a double purpose. These recesses may receive small corrugated plates K, to form a rough surface, against which the levers I will hold the iron to prevent slipping.

The upper surfaces of the beds are level and in the same plane, so that when the plates K are used only straight bars of iron can be upset.

When curved iron-such as tires, &c.-is to be upset, each bed is provided with an auxil iary bed, L, the upper surface of which is slightly concave. This auxiliary bed has on its under side a projection, (I, to fit in the, recess w in the main bed, and in its upper surface is a recess, y, to receive the corrugated plate K,as shown.

To the side of the movable bed D is attached a shear-blade, M, and in its end is a hole for the insertion of a punch, N, which may be held in place by a set-screw or other suitable or convenient means.

In the stationary bed 0 are made side grooves,

a to receive a flanged block, 0, having the other shear-blade, M, attached thereto. This is of course to be used in connection with the blade M. 7

When the punch N is to be used the block 0 is removed and another block, P, inserted in its place. This block P has on'its outer side a dovetailed recess to receive a die, B.

On the back of the block P is -a vertical groove, h, and a large hole, t, is made from this groove into the front recess at such a point that when the die R is inserted the hole in said die will come opposite the hole 2'. The piece of metal punched out will pass through the hole t' and fall down through the groove It.

Dies of difl'erent size s-thatis to say, with dif ferent-sized holes-may be used in the same block as required, and the punch changed to correspond.

I am aware that removable blocks with ser= rated faces have heretofore been provided with pins which enter recesses in the beds of tireupsettiug machines, and consequently lay no claim thereto.

My improvement consists in providing the beds with recesses adapted to receive the lugs 011 the removable blocks, and also to receive the serrated plates used when operating on straight iron.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The beds G D, provided with recesses :12, adapted to receive the lugs d of the removable blocks L, and also to receive the serrated plates K, substantially as described and shown.

In testimony that I claim the foregoing as my own I ailix my signature in presence of two witnesses.

XVILLIAM HOLDSWORTH.
